   Abstract: Nowadays cloud has become the jargon in computing. Cloud computing is a route for fresh software to increase ability or attach features without borrowing in infrastructure and operating costs. But this evolution and convenience of use revealed a amount of information quality (information correctness) and safety problems to the latest IT-based technology. Cloud storage data integrity is the cloud customers ' most critical issue. Data integrity assurance implies that information will stay as long as it is on the server. Client cannot obtain the information straight from the cloud server physically without all the understanding of the client. Cloud Service Provider (CSP) can change or delete information that is either long-term owned by the client or that uses up a big amount of storage. For its validity, information has to be rectified periodically. Checking correction information is called accuracy of information. Many methods are suggested under different schemes and safety designs to solve problems of data integrity, and all of these have one or many problems. To improve the protected data more security by using of MD6 and SHA3 algorithm to calculate the hash functions and hash values to secure the data integrity. This paper will be comparatively focused on challenges in data integrity techniques.

   Keywords: Cloud Computing, Attribute Based Encryption, Integrity of Data and Security of Data.

   1. INTRODUCTION

      Cloud computing in the terminology at which data collection is outsourced to utility providers and users need not care about any data retention limitations such as how and where information is stored, data security and honesty, etc. External service provider is called CSP (Cloud Service Provider) and it is CSP that guarantees users of all problems linked to data storage. CSP provides storage room on pay-per-use facilities through a network. Cloud computing developed from Grid Computing but it was too quickly making its own unique identification. The essence of cloud computing has performed a crucial part not only in large-scale sectors, as well as in small-scale sectors. It is because information production are far outstripping cloud storage and purchasing fresh hardware whenever extra data storage is needed was a very expensive thing to tiny companies. So it's good to outsource CSP's storage task. Storage outsourcing helps to reduce stock, servicing and staff expenses. It also makes sure important information is stored reliably by maintaining various versions of the information, thereby decreasing the opportunity of information loss due to hardware errors. Given all other benefits of cloud computing, there are many important safety issues which need to be studied and resolved widely,

      but cloud computing can become a secure answer to the issue of maintaining local data storage.

   2. RELATED WORK

      Sahai and Waters implemented attribute-based encryption [1]. Two sorts of ABE exist: fundamental ABE procedure and CP-ABE approach. Each ciphertext is related to a set of features and the secret key for each customer is related to only one attribute of the access structure. A client may decode a ciphertext just if the client's mystery significant access structure is happy with set of ciphertext qualities. This entrance control usefulness can be extremely amazing, yet in addition expensive. A size of a ciphertext is consistent with the amount of characteristics connected with that in existing KP-ABE constructions and the cost of decryption becomes proportional to the Quantity of characteristics used when decrypting. The characteristics of the KP-ABE system are: completely expressive safe in the current model; ciphertext of constant size and fast decryption.

      Yang, X. Jia, K. Ren, R. Xie, and L. Huang [2] Cloud stockpiling encourages the two people and ventures to cost adequately share their information over the Internet. This additionally conveys troublesome difficulties to the entrance control of shared information since few cloud servers can be completely trusted. The CP-ABE is methodology that empowers the information proprietors themselves to put negrained and cryptographically implemented access power over out sourced information.

      P. K. Tysowski and Hasan, [3] They proposes high volume and speed of gigantic data, it is an effective choice to store colossal data in the cloud, in light of the way that the cloud has capacities of securing immense data and planning high volume of customer get to requests. Quality Based Encryption is a technique to guarantee that enormous data in the cloud begins to finish security.

      Z. Zhou and D. Huang, [4] Portable contraptions, for instance, propelled cells are still comparatively frail as opposed to work regions in regards to computational capacity, accumulating, etc., and isn't Prepared to meet the increasing customer requirements. Planning compact enrolling and conveyed registering, portable distributed computing phenomenally expands the farthest point of the flexible applications, anyway it procures various troubles in circulated figuring, e.g., data security and data dependability. The new sort based go-between re- encryption to design a sheltered and gainful data apportionment structurbe in MCC, which gives data

      insurance, data decency, data approval, and exible data dispersal with access control.

      Cloud administration providers give clients a reflection of boundless extra space to have the information [6]. It encourages customers to diminish money related overhead of information the board by moving the neighbourhood the executives framework into cloud servers. The security concern turns into the fundamental limitation. The information privacy technique is utilized to scramble data reports before the customer transfers the encoded data into the cloud. It proposes an Identity based ring mark for information partaking in the distributed storage gatherings. The reason for this plan is to give forward security to gigantic cloud information sharing.

   3. PROPOSED SYSTEM

      The proposed system is MD6 and SHA3 Algorithm is to ensure data integrity. This Algorithm will help the finding the hash functions and hash values. Data owner to finding the hash features data user can retrieve the data to compute the same hash features user to securely store and exchange web information. Data Integrity Verification for information deposited on cloud computers is one of the main safety controls. Cloud users have ensured data security through frequent data integrity checks. In this document, we provide an efficient and effective DIV strategy that provides an audit framework that is effective and safeguarding privacy. A multi-power version of the Paillier cryptography scheme with homomorphic tag is the primary construction blocks of our method. A distinctive and verifiable value is assigned to each information block by the Paillier cryptography scheme including homomorphic tag, which helps perform dynamic allocation operations in the cloud setting. It is a method of verifying the information modified by the hacker or information user that will give the notification as the information has been altered.

      Architecture

      1. Key Generation: information holder utilizes Data Encryption Standard calculation for age of blend of open and personal lock on its own. Trusted Authority additionallyutilizes DES calculation for producing Primary pair their own. TPA's Pkl and personal code and the proprietor of this information is pk2, while TPA's open key is dl and data proprietor's open principal becomes d2.

      2. Key Sharing: TPA primary series {pkl, dl} at the DO

         {pk2, d2} Mobile Device TPA Key gathering. Just the TPA Public Key is traded among Data Owner and Trusted Authority by means of a protected stream.

      3. Encryption: Encryption: First, The information proprietor utilizes open key (d2), E(F, d2) encryption message/document (F) and rather produce the encoded H(E(F, d2) content configuration. The scrambled report is presently re-encoded with TPA E(E(F, d2), dl) government code (dl). These two bundles are presently being included and the outcome is being sent to TPA. TPA stores the message's scrambled hash highlight to ensure data consistency. TPA unscrambled by its private key the bundle E(E(F, d2),dl) got. TPA Makes one of a kind catch for encryption delivered after encryption on the E(F, d2) signal. This produced key is put away by TPA for performing unscrambling in future. The result is sent to the internet capacity.

      4. Decryption: When required to approve information precision, the {Encrypt (E (F, d2))} encoded bundle will be sent to TPA after the cloud-spared. TPA initially decodes the message by arbitrary key put away by him. At that point TPA produces it's the hash encoded document acquired from cloud. Presently, the hash esteem that it has recorded, TPA is decoded; Comparison of This root amount is unscrambled to the one it produces. At that point TPA gives the report to the owner expressing the rightness or not and the required record as per the result procured.

   4. SECURITY AND PERFOMANCE ANALYSIS The scheme that is suggested verified by two different kinds that is Evaluation of safety and efficiency analyses. Its desired scheme was evaluated by the safety risks that could be available in the security analysis. Here the system is evaluated against its correctness and whether it offers the smart phone user's information with confidentiality and safety. In execution examination the exhibition of proposed plan is investigated concerning the quantity of activities includes in the plan just as the capacity necessity of the plan. Information is scrambled with the incredible encryption calculations; it is essentially difficult to decode it without the symmetric key. We can therefore suggest the assaults on genuine information without comparison closeness keys would not be effective. In the event that it is expected that the keys are stayed quiet and are not available at all, Protection at a certain stage and respectability of information are ensured. On the recommended framework, security examinations are led.

      incorporates the hash work that is encoded and by directing many activity can't be unscrambled by an assailant. In case any individual performs record similarly as hash modifications, the TPA can undoubtedly check them and the aftereffect of the affirmation is changed over to the proprietor.

      Correctness: Just the data proprietor can unscramble the record got In the Power of Confidence in each framework on the grounds that the archive is scrambled by the data proprietor's open key and to decode it, it needs the private catch of the information proprietor, which is just distinguished by the proprietor. The correctness of the suggested system is guaranteed. If the proprietor wishes the document placed on the cloud, the TPA requests it to order from the Supplier for internet processing and performs Operations to monitor the validity of information.

      Authentication: The information proprietor utilizes his sign your own catch to the content mark, nobody else can sign the message, so TPA can promptly look at if the record proprietor of the message was confirmed or not. In the event that another person the server party and perform change on the record after that he transfers the document On the computer, he requires the personal number of the proprietor to sign the report, and after that the TPA can undoubtedly see if that individual is a validated individual or not.

      Confidentiality: The record moved between the Recognized Power and Online storage Supplier is indexed and confused, which keep away from Cloud Storage Provider knowing the substance of the document and guarantees protection and secrecy of the document. At the point when the record is on the channel it isn't the plain content, it is scrambled by some encryption component, so any interloper couldn't get any data from the document in transmit and can't utilize that record for possess advantage. The encoded report is put in the cloud in this framework, so CSP was not able get any information about the record contained in the cloud.

      Attack: In web, clients can be assaulted from anyplace. When the web is empowered to convey a sign, there is a risk that any assailant may assault the sign. The nearness of private data in the cloud must be by means of web in this framework. Proprietor stores their information in the cloud through web and can get data by means of the web.

      During information move, an aggressor might be accessible, so transmission is encoded awry in this recommended framework and this additionally utilizes one time hash work. Information move additionally

   6. CONCLUSION

At the point when an asset bound cell phone stores its information on the cloud, there is consistently a noteworthy worry about whether the cloud specialist co-op stores the records accurately. Security is the primary issue in portable distributed computing. The proposed instrument offers a wellbeing framework to utilize MD6 calculation just as hash capacity to verify the data in versatile distributed computing. This exploration paper proposed a System of secrecy and Data respectability placed its narrow cloud back. This examination paper recommended a System of secrecy and Data trustworthiness put away in the convenient cloud. The suggested system utilizes MD6 algorithms with other procedures for encryption, decryption to safeguard the information so that no cloud information leakage can be done. The encryption used in this system that provides protection of information during transmission. Consumers could assume which the data is safe because the encrypted data is stored. In the plan record, just in encoded structure is moved over the channel, which lessens the issue of data divulgence. No, third individual or interloper can get the document since that individual don't knows the key of information proprietor. There is consistently a degree for development in each field of work, so here too. Every one of the estimations and checks are downloaded to TPA, with the goal that some work should be done to permit TPA simpler. Future work could be investigating the utilizations of different structures connected in secure capacity administrations of portable cloud condition. There is some work this can be accomplished to diminish the versatile terminal overhead.

In the proposed framework that offers confirmation of information trustworthiness all through the cloud that can be utilized by customer to check data exactness in the cloud. Broad evaluation of wellbeing and effectiveness Proves that the framework proposed is very productive and versatile to assaults of vindictive data and adjustment.
